. jury which may result from a sudden acceleration of speed from any cause; and the object of my invention is to locate the mechanism which operates the brake upon the arbor of the drive= wheel, inside ofthe belt, where it is less exposed to injury, more simple in its construction, and therefore less expensive and more durable, and where its operation is entirely independent ofthe drive-wheel.

In the accompanying drawings, in which similar letters refer to similar parts throughout the several views, Figure 1 is a side elevation of speed-regulator embodying my invention. Fig. 2 is a vertical section ot the same.

.A is the arbor of the drive-wheel B. On this arbor, and between the drive-wheel and the power,is hung the loose pulley C,from the inside of which extends the tubular drumD. This drum is designed for the rope which operates the lever O, which is so arranged upon the power or otherwise as to force a pad or brake,

P, against the rim of the drive-wheel B, for the purpose of checking the rapidity of its revolution.

E is a rod having a weight, e, on its outer end. Itis attached to the inside of one or more of the spokes of the drive-wheel B by means ot'loops ff', through which it is designed to slide.

gis a spring coiled around the rod Il, between its adjusting-nut hand lthe loop f, its tension being regulated by the adjustment of the nut 7b.

I is a bell-crank lever, pivoted att' to the inside of the spoke of the drive-wheel B, adjacent to the one to which the rod E is attached.

'One of its arms is slightly curved on its lower face 'to yform a brake-pad, K, upon the loose pulley C, the other vbeing secured to the lower spondingly depress the brake-pad K upon the rim ofthe pulley C. j

In operation, the vrod Efis so placed that the pad Kfdoes not impinge upon the pulley C, the rope around the drum D being also sut'- ciently loose to keep the brake O free from the drive-wheel B.- As 'the revolutions of the drive-wheel become accelerated the weight c of the rod E is moved outward by centrifugal force, carrying forward 'with it the lower arm of the lever I, to which itis attached, thereby causing the pad K to -bear upon the loose pulley C andv the pulley to revolve upon the arbor of the drive-wheel B. This immediately causes the brake-rope to wind around the drum D until by the tightening ofthe rope the leverbrake O,to`which it is connected, is forced.

against the rim of the drive-wheel B, the effect of which is to check the speed of the drivelwheel B until, the centrifugal force being reduced, the action of the spiral spring draws the rod E back to its normal position, which at once relieves theloose pulley C from thepressure of the pad K, loosens the rope on the drum D, andmoves the lever-brakePfrom the rim of the drive-wheel B. Greater or less centrifugal force, required to operate the weight e, is obtained by turning forward or backward thegadjusting-nut h, thereby increasing or diminishing the tension of thespring g, so that the motion of the drive-wheel B can be readily adapted to the character of the work required ofthe power. At the same time, the regulating device being located where it is out of the way, andleast liable to be injured, and where no complicated mechanism is necessary to ren- 1 IOO with a. rope and loose pulley and weighted arms upon the drive-wheel. 1 therefore do not claim such a combination, broadly; but

What I do claim as my invention, and desire to secure by Letters Parent, is-

1. The eombiuetiomin a horse-power speedregulator, of the drive-Wheel B, bell-crank lever I, with the Weighted rod E, sprimgr g, loose pulley C, having a rope-drum, D, hung on the arbor A, and between the drive-wheel and the motive power, and connected by a. rope to e brake-lever, P, operating on the drive-Wheel, substantially as and for the purpose described.

2. The loose pulley G, having a tubular drum extension, D, placed between the drivewheel B and tbe motive power, in combina-
